How can you achieve decent clock accuracy in microcontrollers (e.g., max 1 second drift in a...

Basically this is my observation: Internal RC clock - drifts by ~10 seconds within 24 hours Crystal oscillator 8 MHz - using default interrupt delays calculated by MPLAB MCC drifts by ~10 seconds within … few days Crystal oscillator 8 MHz - using calibrated delays per each crystal individually drifts by ~10 seconds within a month Crystal oscillator 16 MHz - using calibrated delays per each crystal individually …
